Two members of an indigenous Quechua community in Bolivia's highlands will be tried for murder, accused of leading a mob that buried alive a teenager suspected of raping and killing a woman.

Casiano Sandi and Felicia Vargas have also been charged with inciting a mob and criminal association, prosecutor Milton Jara said.

Jose Luis Barrios, the chief prosecutor in Potosi province where the lynching took place, said police had identified the dead youth, 17-year-old Santos Ramos, as a suspect for the attack on a woman aged 35 in a Quechua community near the district of Colquechaca. He said more than 200 community members seized Ramos and buried him alive alongside his alleged victim on Wednesday night.

Ramos was brought bound to the woman's funeral and thrown into her grave with her coffin, said a reporter for a local radio station.

Colquechaca is a town of 5000 people, around 200 miles south-east of Bolivia's capital, La Paz.

Lynchings sometimes occur in rural and poor parts of Bolivia where police and other authorities are scarce.

Bolivia's 2009 constitution recognises indigenous justice and allows com-munity leaders to mete out punishment, but only for for minor infractions.
